Standard Abrasives™ Quick Change Buff and Blend HS Disc, 840458, Medium, TR, Blue, 3 in, Die Q300V, 25/inner, 100/case

High Strength non-woven nylon material ensures that our Standard Abrasives™ Quick Change Buff and Blend HS Disc maintains stiffness and won't tear or fray when faced with challenging edgework or irregular surfaces. Within the Standard Abrasives™ Buff and Blend product line, the HS Disc offers the best performance for cleaning and light deburring while achieving a final finish or polished piece.

Three Grades Well-Suited for Deburring and Finishing Irregular-Shaped Parts
Among the four Standard Abrasives™ Buff and Blend materials, HS material is the most stiff, durable and aggressive. Given its strength and durability, our Standard Abrasives™ Quick Change Buff and Blend HS Disc is a good match for irregular-shaped parts, such as pipe threads, the edges of molded glass containers, and non-ferrous die cast molded parts. It removes small, stubborn burrs and cuts sharp to produce a consistent finish. Non-woven construction makes the material responsive to contours and extrusions, so it is unlikely to gouge or mar the substrate while achieving an aggressive cut.

Aluminum oxide abrasive grain bonded to the nylon strands produces a uniform scratch pattern - perfect for satin or grain finishing. Use a Standard Abrasives™ Quick Change Buff and Blend HS Disc for final finishing on brass, steel, bronze, pewter, and stainless steel, as well as plated plastics.

When a very fine high luster and decorative finish is desirable on pieces such as builders hardware, choose the HS Disc in MED or VFN grade. For applications that may require a faster cut or coarser finish, choose the CRS grade disc. The coarser scratch pattern of the CRS disc also makes it ideal for satin and grain finishing applications, as well as blending and cleaning surface imperfections.

When your application calls for a lighter-duty disc or if the final finish isn't as critical, we suggest our Standard Abrasives™ Buff and Blend GP or HP Disc. For off-hand and automated finishing processes, we recommend the loftier Buff and Blend HS-F Disc.

Load-Resistant Construction Boosts Life and Performance
Standard Abrasives™ Buff and Blend products are load-resistant to keep you cutting with fresh mineral. The gaps in the open web allow unwanted swarf to escape. Consequently, less debris clogs the abrasive, so the mineral can stay fresh, keep cutting sharp and deliver a consistent cut over the life of the product. As the fibers break down and fresh mineral is exposed, it reduces the likelihood of dull or blunt mineral smearing the surface, contributing to cleaner surfaces and less re-work. Furthermore, manual fatigue that may result from applying heavy pressure to a dull abrasive is reduced.

Quick Change Discs Provide Added Convenience and Time Savings
Standard Abrasives™ Quick Change Buff and Blend Discs are available in disc diameters up to 5 inches. Quick change discs allow tool-free swap outs, maintain secure attachment at high speeds, and save operators time when switching discs between grades or applications. Easy fastening and swapping of discs enhances tool efficiency and worker productivity. Choose the disc compatible with your TR or TS holder pad. TR discs have a nylon threaded male hub that easily threads onto TR or 3M™ Roloc™ type holder pads with a turn of the wrist, and the TS system has a metal hub that fastens to its holder pad with a simple twist.

The Many Benefits of Standard Abrasives™ Buff and Blend Products
Standard Abrasives™ Buff and Blend products invigorate deburring, cleaning, blending and finishing applications by helping operators reduce finishing steps, minimize costs and achieve greater throughput. Each Buff and Blend product and grade offers unique benefits, so operators can choose from a versatile range of options to ensure superior performance on specific applications.
